Hi,
I am using a nested cobol program.In the main program I have declared some working storage fields.Can I use the same fields in the nested program without declaring it again in the nested program?If so,how the nested program will be taking those feilds from the main program?
Thanks

Is it a called prorgram.. i.e to it subprogram u r calling from main program? |

What do you mean by nested program? a subprogram?
If you mean subprogram, then you need to declare variables there too..
Please give some more informatil about your question.. |

Nested program is like one program inside another program.We used to write the nested program inside the main program itself.It starts with a seperate identification division inside the main program.
Thanks

Yes. But the other way can't be done (i.e., variables declared in sub-program cannot be reffered in the main program).
If you have any common variable, local variable overrides the global/main program declaration. |

Hi Murali,
Thanks for the reply.
But how the nested program can use the variables declared in the main program without declaring the main program varaibles as global?In my program none of the fields are declared as global.
Regards,
Sreelekshmi |

Is this discussion going on about COBOL? Just needed to confirm, because 'jargon' looks different.  |

What is the basic idea behing such nested programming 
Is it a client requirement or merely of theoritical interest  |

Yes, it is about cobol language.

By default any variable declared in the nested program is visible to that level as well as sub level. |

| Please include an extremely short example of your nested COBOL program. Just the essentials, so we can see the structure, and how this variable is known at different levels. Thanks. |

| OP liked answer from murmohk1 and he too seems well versed with 'nested COBOL programs'. May be he can help us understanding nested COBOL program. |

| The Enterprise COBOL Programmer's Guide has a lot of stuff I never associated with COBOL (dinosaur...), really kind of neat. |
